When you delete the game using either the delete key or the right click menu option, it appears as faded and a line drawn through it but the games are marked only for deletion.

 

 

You can repeat the operation to unmark them.

 

Here a description how it works.

 

Open the database that has the game you want to delete.

 

Click on the game you want to delete.  

 

Press the delete key on your keyboard or Rightclick -  Edit - Delete

 

 

The game should now have a line through the information.

 

Go to the database window. And select the database with the marked games.

 

For the database you want to finish deleting games from select Menu Maintenance – Remove Deleted Games.
